python-backoff

python-backoff is a Python library providing function decorators for configurable backoff and retry strategies. It allows you to wrap functions to automatically retry their execution until a specified condition is met, such as handling transient failures from unreliable network resources or external APIs. The library supports both synchronous and asynchronous (asyncio) code, offering various wait generators like exponential, fibonacci, and constant backoff. It is actively maintained, with recent releases in late 2025, and the current version is 2.3.1.
